Proper cooling system maintenance is essential for the performance and longevity of your 2004 Husqvarna WR250.

While the process is straightforward, the WR250 has a few unique points worth noting for owners.
What You Need
- Fresh coolant compatible with aluminum radiators
- Basic hand tools: sockets, screwdrivers, pliers
- Drain pan
- Funnel
- Gloves & safety glasses
- Compressed air (optional but recommended for a full flush)
Step-by-Step Coolant Change Process
-
Preparation:
- Place your bike securely on a stand and allow the engine to cool completely.
- Remove the seat and side plastics if needed to access the radiator cap and lower hoses.
-
Draining Old Coolant:
- Locate the radiator cap and the coolant drain bolt (usually at the base of the water pump or lower radiator hose).
- Place a drain pan beneath the drain bolt. Slowly remove the radiator cap to release pressure, then loosen and remove the drain bolt. Allow all coolant to drain.
- Remove the lower radiator hose if additional fluid remains. For a more thorough flush, use compressed air to carefully blow out any remaining coolant from the system.
-
Inspecting Components:
- Check hoses and clamps for cracks, swelling, or leaks.
- Inspect the radiator fins for damage and clear out any debris.
-
Refilling the System:
- Reinstall the drain bolt and lower radiator hose, ensuring they're torqued to manufacturer specifications.
- Using a funnel, pour the fresh coolant into the radiator until it's nearly full.
- Tip: On the 2004 WR250, gently rock the bike side-to-side to release any air pockets, which can otherwise lead to overheating.
-
Bleeding Air:
- Leave the radiator cap off and start the engine. Let it idle for a couple of minutes, watching for air bubbles.
- Top off coolant as needed, then shut the engine off and replace the radiator cap.
